KALYMENIA RENIFORMIS, 7. “%. 
Gen. Cuar. Frond blood-red, ribless, expanded, carnoso-membranaceous, 
formed internally of three strata; the inzer, of interlacing filaments ; 
the medial, of large, roundish cells; the outer, of minute, vertically 
disposed cellules. Fructification two-fold, on distinct plants: 1, sphe- 
rical masses of spores (favel/idia) semi-immersed in the frond; 2, 
triangularly divided, scattered ¢etraspores. KatymMENta—from xahos, 
beautiful, and ipny, a membrane. 
KatyMenia reniformis; stem short, cylindrical, suddenly expanding into 
a roundish, subsimple or irregularly cleft, somewhat lobed frond ; 
favellidia densely scattered over the surface.

Descr. Root scutate. Stem 4+ to 4 inch long, cylindrical or compressed, sud- 
denly expanding into a roundish, elliptical or reniform frond of a soft, 
-  thickish-membranaceous substance, and blood-red colour, simple, or pro- 
ducing at the margin secondary fronds resembling the primary one in form 
and substance. These vary in breadth from an inch to 6-8 or even 14 
inches, but rarely sport much in form, except when continuing to grow 
after they have been torn by the waves. avellidia the size of poppy seed, 
densely scattered over the frond to which they give a peculiarly gritty feel, 
semi-immersed, containing several clusters of dark-red, oblong, somewhat 
angular seeds, densely packed together. Tetraspores extremely minute, 
scattered among the surface cellules. The structure, as shown at fig. 6, 
consists of three strata; the cer, composed of branched and anastomosing
